Effect Of Temperature On Rate Of A Reaction - Lesson Summary

The rate of a reaction depends on the concentration of its reactants (or) on the pressure in case of gaseous reactants. Along with concentration or pressure, temperature also has a major effect on the rate of a reaction.

The rate of a reaction generally increases with an increase in the temperature.

The Arrhenius equation gives the relationship between the rate constant (k) of a reaction and the absolute temperature (T).

Rate of Reaction ∝ Temperature

According to the collision theory only a small fraction of the collisions produce a reaction. These colliding molecules must collide with the proper orientation with sufficient energy, called threshold energy, which is the energy possessed by reacting species in addition to activation energy.

The energy required by the reactant molecules to reach the transition state is known as activation energy Ea.
